Thread: All good things come to an end.

One of my early rifle reloading adventures was 303 with cast bullets using older CAC once fired brass. Like from the 1950s or thereabouts. I was proceeding very gingerly with only book learning for guidance. I loaded 12 and put them aside. 3 days later, 8 of the rounds necks had split. That's when i went and learned about annealing brass. Did that and no issues. Reloaded those first case 5 times with cast doing load development. Still have them..

Greetings @Jhon,
I had much the same experience but with jacketed projectiles. Your cases were likely late 60's or later vintage. Early sporting CAC cases were Berdan primed with non corrosive primers. These were the first sporting rounds I bought and only realised I couldn't reload them after I started hand loading in the early 70's.
